How to access the galaxy watch health data by independent application

Hello, Im developing an application in health care topic. Im currently using Python + AWS for backend and react native for frontend. I would like to implement the connectivity with samsung galaxy watch to gather information about day rhythm, heart rate etc.
Is there any solution to gather those information automaticly using some type of scripts without exporting the csv files? I would like to have a simple interface to work with the data.

Gear S2, Gear S3, Galaxy Watch, Galaxy Watch Active used Tizen OS and Samsung Health SDK is no longer available for new developers partners
Galaxy Watch4 series uses Wear OS Powered by Samsung and that uses Health services on Wear OS

So there is no common way to get data from all versions of Samsung Smart Watches and no common way to get the data from all the smart watches that tract fitness.

What you need to do is create a Watch app that directly access the sensors one for Wear OS, one for Wear OS Powered by Samsung (AKA Wear OS 3) and a companion app on your mobile.

You need to use Tizen Studio for the older Samsung Smart Watches and Android Studio for the Smart Watches that run Wear OS 2 and Wear OS 3.

Hope this helps,
